sintered what?

[_paralyzed_]

everyones raving about novaks new sintered rotor, can I put this in my 6.5 hv maxx and what does it do? thanks -tha wheelchair pimp

Here is the replacement rotor for the Novak HV motors:

Novak Electronics HV Nickel-Plated Sintered Rotor (550-size)

I can't remember which novak motor comes with the sintered rotor now, but yes you can buy it and slip in right in and it should work great. I hear it will lower the Kv. value quite a bit though, naturally.

performance wise, thanks for the link!

.........my 6.5 has this already??

[ClodMaxx]

if you bought yours as a 6.5 system, it already has the sintered rotor.

i bought it as a system, ran two charges and snapped a rotor, got it back ran 1/2 a charge in a rustler and got it wet, got a faulty replacement sent to me for a 1/4 charge, as it sits right now i've got over $400 into a novak setup with less than 4 charges through it, right now i'm waiting for an inverted motor mount from kershaw designs because i put the diffs in backwards and don't want to tear down my truck

no its just a better rotor and they dont get heat fade, or wear out sooner then a normal one in the heat

atleast with the 540 sized ones:018:

Sintered rotors are nickle plated rotors which are a tad more effecient than regular rotor. All highend motors use them and unlike the novak, they come segmented to handle more heat and power.

I think it depends on when you got your HV 6.5 whether or not it has a sintered rotor. All Novak brushless motors now (since Jan I believe) come with a sintered rotor except the EX series (I think the crawler motor still uses a bonded rotor also). My experience with the sintered vs bonded in the 540 motors is that the sintered gives the following advantages.

1. Runs 15-20 degrees cooler
2. Magnet is much stronger (more torque better braking)
3. Since it runs cooler you can gear it much higher.... I went up 8 teeth on the pinion in my TC and motor barely gets to 130 degrees.
4. Novak's site shows the KV rating did not change but the power output did increase (Watts)
5. The rotor is supposed to handle up to 250 degrees before the magnet will fade... so it should shut down thermally way before any damage is done.

I would imagine what you would see in the 550 cans would be similar.

I think all HV6.5/4.5 motors have sintered rotors. In fact, the sintered rotor allowed novak to be able to release a lower turn motor that could be run on the HV esc.

but it will eliminate the shift selector

Not necessarily, you can work your way around the transmission.
